The guide wheel mechanism 20 is mounted on the main body 10, and the drive wheel mechanism 30 is mounted on the drive mounting member 40. The first end of the drive mounting member 40 is hinged to the main body 10. The pressure regulating mechanism 50 includes a telescopic movable member, the first end of the telescopic movable member is hinged to the main body 10, and the second end of the telescopic movable member is hinged to the second end of the drive mounting member 40. When in use, the guide wheel mechanism 20 is used to slidably mount the main body 10 on the track t, the drive wheel mechanism 30 is used to abut against the track t to drive the main body 10 to move on the track t, and the telescopic movable member drives the drive wheel mechanism 30 to press or loosen with the track t by extending or shortening the drive mounting member 40.
[0024] By applying the technical solution of the present invention, the pre-tightening force generated by the drive mounting member 40 on the drive wheel mechanism 30 is adjusted by extending or shortening the telescopic movable member of the drive wheel mechanism 30, so that the drive wheel mechanism 30 and the track t are effectively pressed together, and the drive wheel mechanism 30 and the track t cooperate to achieve effective and high-precision movement. In subsequent maintenance or overhaul, the telescopic movable member can also be adjusted to shorten to relax the drive wheel mechanism 30 and the track t.
[0025] As an optional implementation, Figure 1 As shown, the pressure regulating mechanism 50 also includes a base 51, which is fixedly mounted on the main body 10, and the first end of the telescopic movable member is hingedly mounted on the base 51.

[0026] As an optional implementation, in the technical solution of this embodiment, the telescopic movable part includes a telescopic rod 52 and a compression spring 53, the first end of the telescopic rod 52 is hinged to the base 51, the second end of the telescopic rod 52 is hinged to the second end of the drive mounting member 40, and the compression spring 53 is installed on the telescopic rod 52 to drive the telescopic rod 52 to extend. When in use, the compression spring 53 drives the telescopic rod 52 to extend, so that the drive mounting member 40 continuously generates a pressing force on the drive wheel mechanism 30, so that the drive wheel mechanism 30 is pressed against the track t, so that the drive wheel mechanism 30 cooperates with the track t to achieve effective and high-precision movement. More preferably, in the technical solution of this embodiment, the telescopic movable part also includes a pressing adjustment member 54, which is installed on the telescopic rod 52. The operator can adjust the force of the compression spring 53 on the telescopic rod 52 by operating the pressing adjustment member 54, so that the force between the drive wheel mechanism 30 and the track t is within a reasonable range.
[0027] As another optional implementation, the telescopic movable part may also be an electric push rod, an electric cylinder or other movable cylinder to realize the adjustment function of the drive mounting part 40.
[0028] More preferably, in the technical solution of this embodiment, the first end of the telescopic rod 52 is hinged to the base 51 through the first rotating shaft bearing 56, and the second end of the telescopic rod 52 is hinged to the second end of the driving mounting member 40 through the second rotating shaft bearing 55. The first rotating shaft bearing 56 and the second rotating shaft bearing 55 allow the telescopic rod 52 to rotate more stably and smoothly. Preferably, a joint bearing 57 is further provided between the second end of the telescopic rod 52 and the second rotating shaft bearing 55, and the joint bearing 57 can provide the second end of the telescopic rod 52 with higher rotation flexibility, thereby avoiding problems such as the telescopic rod 52 being stuck.

[0030] In the technical solution of this embodiment, the driving wheel mechanism 30 includes a motor 31, a transmission mechanism and a driving wheel 32. The motor 31 is connected to the driving wheel 32 through the transmission mechanism. The driving wheel 32 abuts against the track t and drives the main body 10 to move on the track t by rotating.

Specifically, the pulley assembly 34 includes a first synchronous pulley 341, a second synchronous pulley 342, and a synchronous belt 352 connected between the first synchronous pulley 341 and the second synchronous pulley 342. During operation, the motor 31 outputs a suitable torque and speed to the first synchronous pulley 341 through the reducer 33, the first synchronous pulley 341 drives the second synchronous pulley 342 to rotate through the synchronous belt 352, and the second synchronous pulley 342 drives the driving wheel 32 to run through the concentric rotation. As other optional embodiments, the transmission mechanism can also be transmitted by a gear set or other transmission components.

The guide wheel mechanism 20 is installed on the load-bearing main board 11, and the drive wheel mechanism 30, the drive mounting member 40 and the pressure regulating mechanism 50 are installed in the drive box 12. Optionally, in the technical solution of this embodiment, there are four guide wheel mechanisms 20, which are respectively installed at the four corners of the load-bearing main board 11, and cooperate with the drive wheel mechanism 30 located in the drive box 12 to realize the movement of the track robot on the track t. In the technical solution of this embodiment, a four-bar mechanism is formed by the drive mounting member 40, the telescopic rod 52, the drive box 12 and the base 51 connected thereto, and the clamping adjustment member 54, through which the drive wheel mechanism 30 and the track t can be quickly and effectively adjusted to be pressed or loosened. When in use, the compression spring 53 on the telescopic rod 52 drives the telescopic rod 52 to extend.
